Vintage Kinetic Quartz 1980's Calculator Alarm Watch Not Working As Is

Details:

Watch is not working, not sure what the issue is. I put a new battery in it and at first it appeared to work fine (see last photo where I was attempting to set the date, now the watch is no longer working at all). As I was creating this listing I attempted to test it, pressed several buttons trying to figure out how to test the alarm sound, and when I hit somewhere around the 4 and 7 keys the screen went blank and hasn't come back on since. Being sold as is for parts or repair. 101624...
